HINGE-GAINER.

SPECIFICATION forming part of Letters Patent No. 695,355, dated March 11, 1902.

Application filed October 24, 1901` Serial No. 79,863. (No model.) Y

To rtZ whom t may concern:

, Be it known that I, RICHARD BRYANT VARD, a citizen of the UnitedStates, residing at San Marcos, in the county of Hays and State ofTexas, have invented a new and useful Hinge-Gainer, of which thefollowing is a specification. A

This invention relates to certain improvements in devices of that classemployed for cutting a gain or Inortise in a door-j am or door for thereception of a hinge.

The object of the invention is to provide an improved machine or tool inwhich all of the parts maybereadily and accurately adj usted to cutrecesses of different width, length, and depth, as more fully describedhereinafter.

In the accompanying drawings, Figure 1 is a perspective View of a hinge-gainer constructed and arranged in accordance with my invention. Fig.2 is a sectional plan view of the same on the line2 2 of Fig. 4L. Fig. 3is a longitudinal sectional elevation of the device on the line 3 3,Fig. 4.-. Fig. iis a transverse sectional elevation ofthe device onthe'jline 4 4L, Fig. 3. Fig. 5 is a sectional plan View showin g aportion of the saine on the line 5 5, Fig. 3. Fig. 6 is a detachedperspective view of one of the end cutting knives or chisels.

Fig. 7 is a transverse sectional elevation of a portion of the device onthe line 7 7, Fig. 2.

Similar numerals of reference are employed to designate correspondingpartsthroughout the several iigures of the drawings.

10 10 designate a pair of parallel guidingbars on 'which are arranged apair of longitudinally-adj ustable carriages 11 and 12, said carriagesforming supports and guides for carrying-bars 13, to which the endknives or chisels 14 are secured. The knives or chisels 1a are providedwith lower cutting edges of any desired length, and the blades aresecured to their carrying-bars by one or more screws 15. The bars 13 arerectangular or polygonal incross-section andare adapted tocorrespondingly-shaped guiding-openings in saidv carriages, and at theupper end of each bar is an enlarged head 17, which may be struck by amallet to eiifect the end cuts. Projecting inwardly from each bar is alug 18, against the under side of which bears a suitable spring 19, thelower end of isaid spring being secured at 2O to the carriage and itsupper free end being yieldably engaged with the under side of said lugand serving to return the same to the initial or raised position andwithdraw the cutting-blade from contact with the wood after eachoperation.

On the outer end of each of the carriages is apair of slotted bars 21,horizontally disposed and adjustable lengthwise, a thumb-screw 22 beingpassed through each of the slots and extending into the carriage, sothat said arms may be locked in any position to which they may beadjusted. The bars or arms 21 are arranged in pairs on each carriage,and to the outer ends are secured vertically-disposed and slottedguideways 23, adapted for the reception of the carrier 24 of a rearcutting knife or chisel 25, the upperend of said carrier being providedwith a striking-head 26. This adjustment permits of the movement of therear cutting-chisel to any desired distance from the carriages, and thedegree of adjustment may be ascertained and regulated by suitable gages27 arranged on the outer ends of the carriages and provided with.suitable slots 28, through which pass thumb-'screws 29 for locking thegages in an adjusted position. The face of each gage-bar 27 ispreferably provided with a measuring-scale, as indicated at 31. towardeach other for any desired distance on the guiding-bars 10, and when soadjusted may be locked in position by screws 32,which pass through thefront portions of the carriage and at their inner ends impinge againstthe rear wall of a longitudinal groove 33, formed in the face of one ofsaid guidingbars.

At the front of the carriages 1l and 12 are secured brackets 34, eachbracket 1ceing provided with vertically-disposed spaced lugs 35, havingalining vertical openings for the reception and guidance ot adjlisting-screws 36, the lower ends of which are secured to rectangularguiding -boxes 37. The guidingboxes are held from any lateral orlongitudinal play by vertical plates 33, which are secured to or formedintegral with said boxes and bear against one face of the lugs 35. To

provide for the vertical adjustment of the boxes, a nut 39 is placed inthe recess or The carriages may be adjusted from or ICO 42@ having atone end an inclined notch 4G eut in'its under surface for the receptionof the tapering longitudinal edge ot a mortis-I ing-chisel 45, and atintervals in the barare similar notches 4G, in which may be placed theinclined edges at the opposite sides of chisels of different width. Themortisingchisels are provided with a forward cutting edge 47, as usual,and side cutting edges 44 are also placed on said chisel for the purposeof making a cleaner cut and at the same time to afford a guiding meansfor the chisel during the cutting operation. The outer end of the chiselis preferably provided with a strikinghead 48, as illustrated in Fig. l.

The chisel is held against the plate 42 by a bottom carrying-plate 50,which may be adj usted from and toward the plate 42 by thumbscrews 5l inorder to permit of the introduction between said plates of chisels ofdifferent thickness.

It will be seen that by suitably adjusting the nuts 39 the chisel may beraised or lowered to any desired extent to cut mortises of different.depth for the accommodation of either light or heavy hinges.

v In addition to the adjustment by the bolts 36 and nuts 39 the lowercarriage is held in place-by an end plate 52, secured at the outer endof the carriage l1 and provided with vertical slots' 53 and 54 to permitof ,its Vertical adjustment with respect to said carriage. Through theslot 53 passes a guide-block 55, projecting from the end of thecarriage, or, if desired, a thumb-screw may be substituted for saidguiding-block. A second thumbscrew 56 passes through the slot 54 andpermits of the locking of the plate in any position to which it may beadjusted. The lower portion of the plate is extended laterally and atits outer end is secured by thumb-screws 57 to a block 58, carried bythe lower chiselguide. The plate is further provided with openings 58',through which said thumb-screw may pass to the openings in the block 58when it is desired to adjust the relative positions of the plate andblock. Through the lower supporting-plate 50 extends a thumb-screw 60,Which may be turned into locking engagement with the under side of themortisingchisel 45 When the device is not in use.

In using the device thevarious parts are 'rst adjusted to form a cut ofthe required size and depth. The end chisels are then tapped with amallet or other tool, and the rear chisel 25 is in like manner forceddown to the required depth. The mortising-chisel 45 is then forced in bymallet blowsto remove the chip.

In some cases, as where an exceptionally small cutis to be made, anauxiliaryguide 23 is used in connection .with one of the guides 23 for anarrow rear chisel. The guide 23 is provided with thumb-screws 62, Whichmay bel inserted in any one of a series of rows of openings G3, formedin the rear face of one or of both of the carriages 1l l2.

While the construction herein described and illustrated is the-preferredform of the device, it is obvious that many changes may be made in theform, proportions, size, and

minor details of construction without departing from the spirit orsacrificing any of the advantages of my invention. Y

It will be noted that the plates 42/y and 50 are adj ustably connectedby the thumb-screws 5l, and in order to provide for a movement of bothplates toward and from the vertical cutting-chisels to provide for thecutting of a wide or narrow hinge-seat the brackets 42 are provided withlongitudinal slots 60, and

the plates 42 and 50 are provided with similar slots 6l, arranged at.each end of said plates. Through these several slots are passed screws62, which may be loosened to permit of the movement of said platestoward and from the chisels, the screws being tightened to lock saidplates in any desired position.

Having thus described my invention, what I claim is-* A 1. In a'deviceof the class described,- the combination with the parallel guiding-bars,of carriages adjustably disposed thereon, cutting knives or chiselscarried by said carriages, a lower mortising cutter or chisel, acarriage therefor,and means for adjustably connecting said carriage tothe main carriages, substantially as specified.
